After burnout, controllers were still able to maneuver the vehicle and manipulate the flight controls for several minutes; the aircraft, slowed by air resistance, fell into the ocean. With this flight the X-43A became the fastest free-flying air-breathing aircraft in the world. NASA flew a third version of the X-43A on November 16, 2004.

2024年1月5日 · At nearly 5,000 mph, the March flight easily broke the previous world speed record for a jet-powered (air breathing) vehicle. The X-43A research vehicle was boosted to 95,000 feet for a brief preprogrammed engine burn at …

X-43A是美国国家航空航天局（NASA）旗下德莱顿飞行研究中心（Dryden Flight Research Center）所开发的极音速（Hypersonic）飞行实验机，也是迄今为止人类所造出使用外进气动力的飞行器中，速度最快的纪录保持者，后续版本为X-43B。

X-43A是一架無人駕駛的飛行器，狀似一個滑板，長約3.6公尺。X-43A使用獨特的超音速燃燒衝壓引擎（Supersonic Combustion Ramjet，簡稱為Scramjet）作為動力，這種動力系統屬於內燃機的一種，與傳統高速飛行時所使用的火箭引擎不同，是從

2024年8月15日 · X-43试验机 是美国 国家航空航天局 （NASA）旗下 德莱顿飞行研究中心 （英语：Neil A. Armstrong Flight Research Center） （Dryden Flight Research Center）所开发的 极音速 （Hypersonic）飞行实验机，曾经是 飞行器 速度最快的纪录保持者。 在系列家族中，除了最早开发的X-43A外，还另外有X-43B、C与D型等几种衍生版本。 X-43A的设计图。 X-43A的运作原理。 计算流体动力学 (CFD) 影像是X-43A在马赫数7测试条件下引擎运作的情况。 在2001年6 …

NASA's X-43A or Hyper-X air vehicle achieved a record-breaking speed of close to Mach 10 (12,000km/hr or 7,000mph) in a test flight in November 2004, which was the culmination of a three-flight test program.

The X-43A successfully separated from the launch vehicle and achieved stable free flight throughout the engine test. X-43A Powered Flight (Scramjet Engine Experiment): • The scramjet experiment/fuel on began approximately 5 seconds after separation • The maximum powered Mach number was 9.6 •

The X-43A was powered by a hydrogen-fueled, airframe-integrated scramjet propulsion system. The engine uses gaseous silane (SiH4) as the ignition source for the hydrogen fuel.
